Earlier this week we posted about home-scaled fish farming coming to a Home Depot near you. Yesterday we came across mention of another aquaponics supplier, Portable Farms (www.portablefarms.com) that produces larger greenhouse-based cultivation/aquaponics setups ranging in size from 6′ x 8′ to 90′ x 120′. The greenhouse seems like a good idea since, even in our warm Southern California climate, common aquaponics fish such as tilapia need heated water. Portable Farms owner Colle Davis runs a two acre farm in Escondido California and has been working on his aquaponics system for over 37 years. The tag line “Fish Don’t Fart” refers to the benefits of fish over methane generating cattle.
We skipped over aquaponics in our book since we considered it too expensive and complicated for most people. But perhaps we should give it closer consideration. Aquaponics is profiled in the pioneering urban homesteading book, The Integral Urban House: Self Reliant Living in the Cityand Scott Kellogg and Stacy Pettigrew’s book Toolbox for Sustainable City Living: A do-it-Ourselves Guidewhich comes out of their work at Austin’s Rhizome Collective. What all of these efforts have in common is a permacultural design principle of turning a waste product into a resource and closing a loop. Fish make fertilizer and plants clean water, so why not combine the two?
I’d like to hear stories from ordinary folks who have tried aquaponics on a small scale. If that’s you, leave a comment!
